IMPROVEMENT IN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 191,499, dated May 29,1877; application filed March 15, 1877.

To all whom a may concern:

Be it known that I, THOMAS WHITE, of Quincy, in the county of Adams andState of Illinois, have invented an Improvement in Heating-Stoves andFurnaces, of which the following is a specification:

The nature of my invention relates to certain new and usefulimprovements in the construction of stoves and furnaces, as more fullyhereinafter described.

The object of the invention is to so construct a stove. or furnace thatall or nearly all the heat will be radiated usefully before the productsof combustion reach the chimney, doing away with the necessity of drumsor coils of pipe, such as are usually employed.

.Figure 1 is a perspective view, from the front, of a wood-burningstove, showing my improved construction, and with the stovefront shownin dotted lines, so that the internal construction may be seen. Fig. 2is a like view from the rear side with the back plate removed.

Like letters refer to like parts in each figare.

In the drawing, A represents the shell of the stove, and B the fire-boxor combustionchamber proper. O G are two chambers, one on each side ofthe combustion-chamber at the front end of the stove, and with nocommunication with the fire-box except through openings in the top ofthe respective chambers, and which are disclosed or covered at will bythe slide-dampers D D, which are operated from outside the stove.Horizontal flues E E open into these chambers O O, and afford.communication between them and other chambers F F at the rear end of thestove.

It will be noticed that the chambers O O, F F, and flues E E are allsituated on the outside of the fire-box, and are so arranged as not tointerrupt the directly outward radiation therefrom. The rear chambers FF communicate with the combustion-chamber by means of the openings G G,immediately above which, and below the plane of the upper horizontalflues, are placed diaphragms or plates h h, which prevent anycommunication between the upper and the lower horizontal flues throughthese chambers at the rear. I is a damper, operated from the outside ofthe stove, by means of which direct draft is had from thecombustion-chamber to the exit-pipe J.

In starting a fire in the fire-box, the direct draft should be disclosedby opening the damper I. When the fluel is well ignited this dampershould be closed, when the products of combustion will pass into thechambers F F through the openings G G, and thence through the lowerhorizontal flues to the chambers O C and back through the upperhorizontal flues to the exit J, nearly if not quite radiating all theheat before reaching the latter-named point.

At any time that not so much heat is required in the apartment, andstill more be required than can be had by direct radiation from thefire-box or combustion-chamber, the damper I should be closed and thedampers D D opened, when the products of combustion will escape from thefire-box through said dampers into the upper horizontal flues, andthence to the rear and the exit.

It will readily be perceived that the arrangement of outside fluesconnecting outside radiating chambers may be applied in various ways tomany forms of heating devices without detracting from the directradiation of the stove or furnace, and that dampers may be so arrangedas to control the direction of the currents of the products ofcombustion without departing from the spirit of my invention; and thatthis arrangement of flues, chambers, and dampers may be materiallychanged without such departure. Consequently I do not desire to confinemyself to the form or arrangement shown, but may vary them as differentstyles of stoves or furnaces may require, so long as I preserve thedistinctive features of my invention.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a heating-stove or furnace, and in combination therewith, and withthe fire-box or combustion-chamber and radiating chamoutside chambers GG F F, dampers D D I, openings G G, outside flues E E, and plates h h,arranged to operate substantially as and for the purposes described.

THOMAS WHITE.
